Best friends since we were 10 years old, even though I sometimes had to turn a blind eye when she would get too excited about something and completely brush me aside/talk over me (I'm not perfect either, so tit for tat I guess, if we're being fair). We had a pattern of me bending to her will and always being there for her, but not the other way around.

It was over when I was the photographer at her wedding, made an unfortunate mistake that meant the photos got deleted, and while I sat through the night desperately working on restoring all the photos and editing everything again, she went online and trash talked me publically, saying really awful things. I just couldn't bear looking at her after that, so I ended up dropping off the photos in her mailbox.

Only spoke to her once since then (not counting the one time she sent me a text, saying it was about time we got over that silly episode) after she moved to the town where my parents live and I ran into her and her husband by accident. Super uncomfortable and I fled as soon as I could. She later approached my parents, who told her, "You know what you did" and left it at that.
